An environmental sensor can measure physical quantities associated with a surrounding environment. The environmental sensor includes one or more sensor elements that detect the physical quantities, and a communication unit that transmits, when a physical quantity detected by at least one of the sensor elements included in the environmental sensor changes in accordance with a predetermined rule (S102), a predetermined maintenance signal including unit identification information identifying at least the environmental sensor (S103).
